Superfluid currents in half-moon polariton condensates

18 Mar 2020 Sedov E. S. Lukoshkin V. A. Kalevich V. K. Hatzopoulos Z. Savvidis P. G. Kavokin A. V.

We excite exciton-polariton condensates in half-moon shapes by the non-resonant optical excitation of GaAs-based cylindrical pillar microcavities. In this geometry, the {\pi}-jump of the phase of the condensate wave function coexists with a gradual {\pm \pi} phase variation between two horns of the half-moon... (read more)
